Grouped Tabs in Editor

Grouped tabs in the editor. Hiding and unhiding them is good, but if you need all the tabs it remains confusing. I have several tabs that I could group together (e.g. living room - light, heating, shutter etc.). Google Chrome and other browsers already support this.
That would be my wish for the next release of the editor. But also in the site menu of the dashboard I would welcome groups/submenus.
